# Problem: Write orbital diagrams for each ion and indicate whether the ion is diamagnetic or paramagnetic. a. Cd2+ b. Au+

###### FREE Expert Solution

We’re being asked to classify each ion as diamagnetic or paramagnetic.

Recall that for:

• diamagnetic: all of the electrons are paired

• paramagnetic: at least one electron is unpaired

To do so, we need to do the following steps:

Step 1: Determine the shorthand e config. of the neutral element.

Step 2: Determine the e config. of the ion.

Step 3: Draw the orbital diagram for the outermost sublevel and determine if the ion is diamagnetic or paramagnetic

Note that for a neutral element, Atomic Number = # of protons = # of electrons.
